A couple of comments about issue7092_syntax_imports_v3.diff too:
1) in test_copy you remove (k,v), but left the name 'k' even if now it represent the item and not the key;
2) in test_fractions you should probably use self.fail() instead of an assert;
3) on test_ftp you can use two separate lines and remove the ';';
4) in test_pyclbr there's one extra 'f' in the comment in assertHaskey;
5) in test_xml_etree_c you can either leave callable() and catch the warning or use isinstance(x, collections.Callable) instead (there are also a few more places where callable was used too).
